proxmox cluster “waiting for quorum…”

nach einem freundlichen “pvecm add ip.add.re.ss” um einen weiteren node zu einem proxmox cluster hinzuzufuegen, bleibt der output da stehen:

~# pvecm add ip.add.re.ss
The authenticity of host 'ip.add.re.ss2 (ip.add.re.ss2)' can't be established.
ECDSA key fingerprint is xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx:xx.
Are you sure you want to continue connecting (yes/no)? yes
root@ip.add.re.ss2's password: 
copy corosync auth key
stopping pve-cluster service
backup old database
waiting for quorum...

da musste ich in dem unglaublich guenstigen, managbaren switch von netgear das IGMP snooping abschalten, welches standardmaessig aktiviert ist.
